With the HomeWizard Smartswitch you can make 433Mhz devices available on the Link. The Smartswitch is a 433 MHz transmitter which can be controlled via Wi-Fi through the Link. In combination with Link (with the  HomeWizard lite integration) you can operate all your 433Mhz switches / curtains within the Link app. The range of the Smartswitch is 25 meters (depending on walls and other obstacles). You can integrate multiple Smartswitch with Link   if you want to provide a larger area with 433Mhz coverage.
